[PATCH v5 0/5] ALPM AUX-Less

[Jouni Högander]

This patch set is implementing calculation of ALPM AUX-Less parameters
for Intel HW and writing them in case of AUX-Less is enabled. It is
also enabling ALPM AUX-Less for eDP Panel Replay. Current code is not
allowing Panel Replay on eDP. Patches for this are coming later.

This implementation is only for Panel Replay usage. LOBF (Link Off
Between Active Frames) usage needs more work.

v5:
  - mention AUX Less enable is only on source side in commit message
v4:
  - drop patch adding AUX LESS dpcd defines
  - re-use fast_wake_lines to store aux_less_wake_lines
  - add comment explaining why AUX less is enabled on eDP panel replay
    without any extra checks
v3:
  - use definitions instead of numbers for max values
  - do not use alpm_ctl as uninitialized variable
v2:
  - use variables instead of values directly
  - fix several max values
  - move converting port clock to Mhz into _lnl_compute_*
  - do not set AUX-Wake related bits for AUX-Less case
  - do not write ALPM configuration for DP2.0 Panel Replay or PSR1

Jouni Högander (5):
  drm/i915/psr: Add missing ALPM AUX-Less register definitions
  drm/i915/psr: Calculate aux less wake time
  drm/i915/psr: Silence period and lfps half cycle
  drm/i915/psr: Enable ALPM on source side for eDP Panel replay
  drm/i915/psr: Do not write ALPM configuration for PSR1 or DP2.0 Panel
    Replay
